I finally took my quadrajet off the table and dropped it into my GP. Without any adjustments the A/F mixture is sitting at 13.8. This is why I like the A/F mixture gauge case without it I would have thought the carb is perfect. It's running great and very responsive with the stiffer power piston spring but thanks to the gauge I need to lean it out a little. It's cold, windy and miserable today so I'll do the fine tuning another day..🙂
